What's in the Treatment Process
Chromium-6 is naturally present in Redmond's aquifer geology at 1.23 ppb — 62x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

Good news for Redmond residents. Your water quality is generally good. Most homes in this area do not need a water softener. If you have concerns about lead (especially in buildings constructed before 1986) or chlorine taste, a point-of-use filter is the most practical and cost-effective solution.

About Redmond's Water Supply
Water Utility: City of Redmond Water
Water Source: Deschutes River & wells (Groundwater)
Population Served: 37,566
Hardness: 40 PPM (2.3 grains per gallon)
Redmond draws its drinking water from groundwater sources — Deschutes River & wells. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 38,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Redmond Water's Consumer Confidence Report (CCR) or test your own tap.
